THILL-couPLlNG.

SPECIFICATION forming part of Letters Patent No. 278,339, dated May 29, 1883.

Application tiled October 28, 1882.

To all 'whom it may concern: Be it known thatI, JOHN WILLIAM KELLEY, a citizen of the United States, residing at Manchester, in thecounty of Benningtonand State of Vermont, have Vinvented certain new and useful Improvements in Shaft Couplings for Carriages; and I do hereby declare the following to be a full, clear, and exact description ot' the same.

My invention relates to carriage shafts or poles` made impart-s or sections arranged forl ready connection to ordisconnection from each other, and also to the prevention ot' rattling.

Reference being had to the accompanying drawings, which form a partof this specifica tion- Figure 1 represents in perspective the rear' end of a shaft or` pole with" all the partsjoined for use. Fig. 2 represents in longitudinal section the same, except that the turn-buckle t appears in relief'. Fig. 3 represents the parts disconnected. Fig. 4 represents in perspective a modilication. Fig. 5 represents 'a longitudinal section of the same. l

The shaft S is divided near its rear end into two portions, 1 and 2, having screw-cavities in their respective proximate ends, one with right and the other with leftpitcll. Intothese cavities the screw ends of the turn-bucklet are titted, in order readily to connect the portions 1 and 2 together 'and as readily disconnectthem from each other. The screw-cavity ofthe rear portion, 1, is prolonged vbeyond the screw- (Model thread to the eye e, and contains the packing against the bolt which passes through the eye,

and thus secures the shaft in the usual Inanner to a clip or other device attached to the axle.

1t will be seen that there are no projections at the joints to receive accidental injurious knocks from whiftletrees, &c.

In the modification the portions 1 and 2 are joined at a right angle, or at any desirable angle, and the bolt b takes the place of the turnbucckle t.

I do not claim, broadly, the prevention ot' rattling by means of'a screw working in a slraft, since that feature 4is shown in the patent of Cyrus E. Gillespie, Henry J. Springer, and Frederick J. Springer, N o. 207,115, dated August 20,1878. y

' I claim as myinvention and desire to secure by Letters Patent--V A carriage shaft or pole made in sections ,unitedby a screw, which also presses against the connection with the axle inorder to pre` vent rattling.

ln testimony whereofI liavesigned Iny name to this specification in the presence of two witnesscs.
